bqfft ===== A small library wrapping various FFT implementations for some common audio processing use cases. Note this is not a general FFT interface, as it handles only power-of-two FFT sizes and real inputs. Requires the bqvec library. This code originated as part of the Rubber Band Library written by the same authors (see https://bitbucket.org/breakfastquay/rubberband/). It has been pulled out into a separate library and relicensed under a more permissive licence. C++ standard required: C++98 (does not use C++11 or newer features) * To compile on Linux: Edit Makefile to select implementation, then make test. Do read the notes in the Makefile, and don't attempt to use the default implementation, which is very slow * To compile on macOS: make -f build/Makefile.osx test * Depends on: [bqvec](https://hg.sr.ht/~breakfastquay/bqvec) * See also: [bqresample](https://hg.sr.ht/~breakfastquay/bqresample) [bqaudioio](https://hg.sr.ht/~breakfastquay/bqaudioio) [bqthingfactory](https://hg.sr.ht/~breakfastquay/bqthingfactory) [bqaudiostream](https://hg.sr.ht/~breakfastquay/bqaudiostream) [![Build Status](https://travis-ci.org/breakfastquay/bqfft.svg?branch=master)](https://travis-ci.org/breakfastquay/bqfft) Copyright 2007-2020 Particular Programs Ltd.
